If you use the same Variable in the Loop you change all icons of course. What i normally would do is to add a variable to every List (currentLocation in your case) Item. Then use this variable and change this on click.

Which is the difference between imports and providers in app.module?
Hi,
I’ve seen that in many tutorials that there is a different use of the imports and of the providers section of the file app.module.ts.
@NgModule({
declarations: [AppComponent],
entryComponents: [],
imports: [
BrowserModule,
IonicStorageModule.forRoot(),
....
],
providers: [
StatusBar,
SplashScreen,
...
],
bootstrap: [AppComponent]
})
export class AppModule {}
What should go in the import section and what should go in the providers section?
When I create a new service provider should I put in the providers section?
Because when I create a service provider I’m not putting them in the providers section but I’m importing them in each page:
constructor(
...
private translate: TranslateService,
private settingsManager: SettingsmanagerService,
private wsManager: WsmanagerService,**
) {
Excuse me for these questions, but I didn’t find a good theoric explanation of these concepts in the Ionic documentation.
Thank you very much
Claudio

Thanks for sharing this. Looks like the API is still in progress but it seems to be able to manage files in the file system. Will keep a lookout for this.

Trigger manually ngFor or making it update DOM correctly
Thank you for your response.
I’ve resolved creating a new array with:
this.foodAllergies = […this.foodAllergies, res.data]
Instead of updating the existing one with this.foodAllergies.push(res.data)

Which is the difference between imports and providers in app.module?
As you said a Provider needs to be defined in the provider Section 
Otherwise you will get an Error when you try to create it in the constructor. In the Imports you can import other Modules.
Tipp: Since a Angular Version (i don’t know exactly which one), you can provide your Services automatically with:
@Injectable({
providedIn: 'root'
})
export class SomeService {}

Connection Refused
I am building a mobile app for Android using Ionic + Angular and I implement an OAuth2 workflow.
When the authentication endpoint redirects back to my app, the navigation is blocked showing the following message:
Application Error
net::ERR_CONNECTION_REFUSED(http://localhost/home?code=)
When serving my app with livereload it works fine, probably because a port is added to the url.

Build on iOS with capacitor (xCode) and plugin background-geolocation is not working. Error: redefinition of enumerator 'NotReachable'
Hi,
I know this bug belongs to the cordova-plugin-background-geolocation, but I was wondering if someone here can help me.
I created an issue on github of the project: https://github.com/mauron85/cordova-plugin-background-geolocation/issues/692
In general the build on iOS with capacitor is not working.

i say it often, but i know people don’t want to hear: Sadly there is currently no free, working and maintained Plugin for Background Geolocation. But there is a paid one, which our team decided to buy and it works perfect. Check it out here: https://github.com/transistorsoft/cordova-background-geolocation-lt
As far as i know it works for capacitor too
